lMPROVEMEN-T IN COMPOSING-STICKS.

Specification forming part of Letters Patent N0. 54,979, dated May 22,1866 antedated May 7, 1866.

To all whom it may concern:

Be it known that L'WM. T. TILLINGHAST, of Dayton, Montgomery county,Ohio, have invented a new and useful Improvement in Gomposing-Sticks, ofwhich the following is a full and eear description thereof, referencebeing had to the accompanying drawings, making part of thisspecilication.

The material used in constructing the stick The improvement does awaywith the cross-pieces and screws heretofore used, and in their places issubstituted a clam ping-n ut, which secures the slide B to the back ofthe stick; also, one or more adjustable check-blocks and checking-barattached to the slide in place of the usual devices for measuring theems.

Figure l is a perspective view of my improved composing-stick. Fig. 2 isan elevation of the back side of the stick with the clamping-nut.

A is the stick. B is the gaging-slide. b is the checking-bar. c, c', andc are check-blocks having slots l, 2, and 3. The check-blocks o o c aresecuredin any desirable position by set-screws. In check-block c is amortise, d, which is for the purpose of receiving the point e ofchecking-bar b. Checking-bar b is pivoted to gaging-slide B at f.Through slot a, inthe back of the composing-stick A, passes thescrew-shaft g, which carries the clamping-nut h, screw-shaft g beingfirmly secured to gagin gslide B.

` b, comes in contact with check-block c.

When the stick is used for setting full measure, as fornewspaper-column, the slide B is thrown back until the point e,checking-bar Since all printed columns are not of the same measure, thecheck-block o may be readily moved by loosening its set-screw andafterward tightening it when the desired position has been given thecheck-block. The clamping-nut thus secures the gaging-slide B inthedesired position.

When one-third measure is required the slide B is moved forward untilthe point e, har b, is inserted in the mortise d in checking-block o.For one-half measure the point e of barb abuts against the front end ofcheokingfblock c. When the measure requires a long stick and isconstantly varyin g the check-blocks o, c', ando" may he dispensed withand reliance placed upon the slot a and clamping-nut h. 1

Having described my invention, and made clear its advantages, I make thefollowing claim y The gaging-slide B, screw-shaft g, and clamping-nut h,in combination with check-blocks c c o and checking-bar b, constructedand operating as above shown, and for the purpose set forth.
